A method relative to an optical information storage medium including a lead-in area, a lead-out area, and a user data area between the lead-in and lead-out areas and in which user data is recorded. Pits are formed in the lead-in area, the user data area, and the lead-out area, and a track pitch in all or a portion of the lead-in area is different from a track pitch in the remaining area of the optical information storage medium.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of transferring data with respect to an optical information storage medium, the medium comprising a lead-in area having a first subarea and a second subarea, a lead-out area, and a data area formed between the lead-in and lead-out areas and in which a predetermined data is recorded, the method comprising: transferring a first data with respect to the first subarea of the lead-in area having a first track pitch between adjacent tracks; and transferring a second data with respect to at least one of the second subarea of the lead-in area and the data area of the optical information storage medium, the second subarea of the lead-in area, the data area, and the lead-out area each having a second track pitch between adjacent tracks, and the second track pitch being other than the first track pitch, wherein the lead-in area having the first subarea and the second subarea, the data area, and the lead-out area are arranged in sequence, and the data area is not positioned between the first subarea and the second subarea, wherein the first subarea comprises optical information storage medium-related information, and wherein the lead-in area, the lead-out area, and the data area comply with a single disc format.
2. The method of claim 1 , wherein the first subarea and the second subarea are contiguous in the lead-in area.
3. The method of claim 1 , wherein the optical information storage medium-related information includes a type of optical information storage medium.
4. The method of claim 1 , wherein the optical information storage medium-related information includes a number of information recording layers.
5. The method of claim 1 , wherein the optical information storage medium-related information includes a size of the optical information storage medium.
6. The method of claim 1 , wherein the optical information storage medium-related information includes information regarding reproducing speed or recording speed.
7. An optical information storage medium comprising: a lead-in are having a first subarea and a second subarea; a lead-out area; and a data area formed between the lead-in area and the lead-out area and in which a predetermined data is recorded, wherein the first subarea of the lead-in area has a first track pitch between adjacent tracks and the second subarea of the lead-in area, the data area, and the lead-out area have a second track pitch between adjacent tracks, wherein the second track pitch is different than the first track pitch, wherein the lead-in area having the first subarea and the second subarea, the data area, and the lead-out area are arranged in sequence, and the data area is not positioned between the first subarea and the second subarea, wherein the first subarea comprises optical information storage medium-related information, and wherein the lead-in area, the lead-out area, and the data area comply with a single disk format.
8. The optical information storage medium of claim 7 , wherein the optical information storage medium-related information includes a type of the optical information storage medium.
9. The optical information storage medium of claim 7 , wherein the optical information storage medium-related information includes a number of information recording layers.
10. The optical information storage medium of claim 7 , wherein the optical information storage medium-related information includes a size of the optical information storage medium.
11. The optical information storage medium of claim 7 , wherein the optical information storage medium-related information includes information regarding reproducing speed or recording speed.
12. An apparatus to optically transfer data with respect to an optical information storage medium that comprises a lead-in area having a first subarea and a second subarea, a lead-out area, a data area formed between the lead-in area and the lead-out area and in which user data is recorded, the apparatus comprising: an optical unit to emit light to transfer data with respect to the optical information storage medium; and a controller to control the optical unit to transfer a first data with respect to the first subarea of the lead-in area having a first track pitch between adjacent tracks and a second data with respect to the second subarea of the lead-in area, the lead-out area, and the data area each having a second track pitch between adjacent tracks, wherein the first track pitch is greater than the second track pitch, wherein the lead-in area having the first subarea and the second subarea, the data area, and the lead-out area are arranged in sequence, and the data area is not positioned between the first subarea and the second subarea, wherein the first subarea comprises optical information storage medium-related information, and wherein the lead-in area, the lead-out area, and the data area comply with a single disk format.
13. The apparatus of claim 12 , wherein the optical information storage medium-related information includes a type of the optical information storage medium.
14. The apparatus of claim 12 , wherein the optical information storage medium-related information includes a number of information recording layers.
15. The apparatus of claim 12 , wherein the optical information storage medium-related information includes a size of the optical information storage medium.
16. The apparatus of claim 12 , wherein the optical information storage medium-related information includes information regarding reproducing speed or recording speed.
17. The method of claim 1 , wherein the single disk format is CD format of DVD format.
18. The optical information medium of claim 7 , wherein the single disk format is CD format or DVD format.
19. The apparatus of claim 12 , wherein the single disk format is CD format or DVD format.
20. The method of claim 1 , wherein the first track pitch is greater than the second track pitch.
21. The method of claim 1 , wherein the first subarea, the second subarea, the data area and the lead-out area are sequentially contiguous in the optical information storage medium.
22. The optical information storage medium of claim 7 , wherein the first track pitch is greater than the second track pitch.
23. The optical information storage medium of claim 7 , wherein the first subarea, the second subarea, the data area and the lead-out area are sequentially contiguous in the optical information storage medium.
24. The apparatus of claim 12 , wherein the first track pitch is greater than the second track pitch.
25. The apparatus of claim 12 , wherein the first subarea, the second subarea, the data area and the lead-out area are sequentially contiguous in the optical information storage medium.
